Hi!

I've got an Asus u403SA notebook with the same elan touchpad, recognised
in xinput --list as ''ELAN1000:00". Please let me share my experiences,
because I think I'm in the same boat:

In ubuntu 15.10 with stock 4.2.x kernel the touchpad works with PS/2
emulation mode, so this is why multitouch not works. The official
support merged in kernel 4.3x, so with this kernel i've got a fully
functional touchpad identified in xinput --list as "elan touchpad", but
after a while (minutes, sometimes hours) the touchpad completely freezes
with this message in syslog:

Jan  5 20:55:27 darkslide-notebook kernel: [ 1531.867948] i2c_designware 808622C1:03: Unknown Synopsys component type: 0x00000000

I think this is NOT the same bug what mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=108581
and in 
http://pkgs.fedoraproject.org/cgit/rpms/kernel.git/tree/0014-mfd-intel-lpss-Pass-SDA-hold-time-to-I2C-host-contro.patch?id=d2ede0b2227fc00e3c80bdd4043245332c3047a8

What can I do to help in problem solving? What output you need?

Title:
  Enable full touch support for ELAN0100 touchpad

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hey,

  there is no full touch support for ELAN0100.  It looks like the system
  recognizes the pad as a normal mouse.  The same problem already
  appeared for the ELAN0600 pad as you can see here :
